is there some science on do polls actually shape the election itself? >> i don't think there's very much evidence that polls shift the election. if they did, i think we would see, you know, a clearer sign of that. what i think the public reacts to that is momentum, i think a lot of voters are like the people that aren't sure or are sure what they want for dinner but won't say it in a crowd necessarily. when someone says what they want, they jump out and say i want kfc tonight. >> i'm so glad you said that, because that sounds delicious. >> a lot of voters after the debates aren't sure whether they like bahama that much or whether i like him enough to say it. they're still voting for him. when the job numbers show him doing better, maybe they feel compelled to come back to the side. >> isn't that the same thing when polls move towards the direction, it's momentum and others get swept up in the momentum. >> i'm sorry. say again? >> when the polls move in a certain direction, that represents momentum and others get swept up in the wake of that momentum? >>
